The problems of observing the near infrared spectrum of Venus, using a twelve inch balloon-borne telescope, are assessed. Considerations of the integrated signals available in the desired resolved width of approx. 0.1 microns in the wavelength region visible to 3 microns, show the need for multiplexing. Spectrometric systems of this type are discussed and a dispersive spectrometer using a multi-channel coded disc in the emergent focal plane is shown to possess certain advantages over the others in this type of problem.
